FIELD OF THE INVENTION

The invention relates to compounds, compositions, and methods for the treatment of human immunodeficiency virus (HIV) infection. More particularly, the invention provides novel Capsid inhibitors, pharmaceutical compositions containing such compounds, and methods for using these compounds in the treatment of HIV infection.

The invention also relates to methods for making the compounds hereinafter described.

BACKGROUND OF THE INVENTION

Acquired immunodeficiency syndrome (AIDS) is the result of infection by HIV. HIV continues to be a major global public health issue. In 2015, an estimated 36.7 million people were living with HIV (including 1.8 million children)—a global HIV prevalence of 0.8%. The vast majority of this number live in low- and middle-income countries. In the same year, 1.1 million people died of AIDS-related illnesses.

Current therapy for HIV-infected individuals consists of a combination of approved anti-retroviral agents. Close to four dozen drugs are currently approved for HIV infection, either as single agents, fixed dose combinations or single tablet regimens; the latter two containing 2-4 approved agents. These agents belong to a number of different classes, targeting either a viral enzyme or the function of a viral protein during the virus replication cycle. Thus, agents are classified as either nucleotide reverse transcriptase inhibitors (NRTIs), non-nucleotide reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), integrase strand transfer inhibitors (INSTIs), or entry inhibitors (one, maraviroc, targets the host CCR5 protein, while the other, enfuvirtide, is a peptide that targets the gp41 region of the viral gp160 protein). In addition, a pharmacokinetic enhancer (cobicistat or ritonavir) can be used in combinations with antiretroviral agents (ARVs) that require boosting.

Despite the armamentarium of agents and drug combinations, there remains a medical need for new anti-retroviral agents. High viral heterogeneity, drug-associated toxicity, tolerability problems, and poor adherence can all lead to treatment failure and may result in the selection of viruses with mutations that confer resistance to one or more antiretroviral agents or even multiple drugs from an entire class (Beyrer, C., Pozniak A. HIV drug resistance—an emerging threat to epidemic control. N. Engl. J. Med. 2017, 377, 1605-1607; Gupta, R. K., Gregson J., et al. HIV-1 drug resistance before initiation or re-initiation of first-line antiretroviral therapy in low-income and middle-income countries: a systematic review and meta-regression analysis. Lancet Infect. Dis. 2017, 18, 346-355; Zazzi, M., Hu, H., Prosperi, M. The global burden of HIV-1 drug resistance in the past 20 years. PeerJ. 2018, DOI 10.7717/peerj.4848). As a result, new drugs are needed that are easier to take, have high genetic barriers to the development of resistance and have improved safety over current agents. In this panoply of choices, novel mechanisms of action (MOAs) that can be used as part of the preferred antiretroviral therapy (ART) can still have a major role to play since they should be effective against viruses resistant to current agents.

Certain potentially therapeutic compounds have now been described in the art and set forth in Blair, Wade S. et. al. Antimicrobial Agents and Chemotherapy (2009), 53(12), 5080-5087, Blair, Wade S. et al. PLoS Pathogens (2010), 6(12), e1001220, Thenin-Houssier, Suzie; Valente, Susana T. Current HIV Research, 2016, 14, 270-282, and PCT Patent applications with the following numbers: WO 2012065062, WO 2013006738, WO 2013006792, WO 2014110296, WO 2014110297, WO 2014110298, WO 2014134566, WO 2015130964, WO2015130966, WO 2016033243, WO2018035359, WO2018203235, WO 2019161017, and WO 2019161280.

What is now needed in the art are additional compounds which are novel and useful in the treatment of HIV. Additionally, these compounds should provide advantages for pharmaceutical uses, for example, with regard to one or more of their mechanisms of action, binding, inhibition efficacy, target selectivity, solubility, safety profiles, bioavailability or reduced frequency of dosing. Also needed are new formulations and methods of treatment which utilize these compounds.

The salts of compounds of Formula I and Formula II are pharmaceutically acceptable. Such salts may be acid addition salts or base addition salts. For a review of suitable pharmaceutically acceptable salts see Berge et al, J. Pharm, Sci., 66, 1-19, 1977. In an embodiment, acid addition salts are selected from the hydrochloride, hydrobromide, hydroiodide, sulphate, bisulfate, nitrate, phosphate, hydrogen phosphate, acetate, benzoate, succinate, saccharate, fumarate, maleate, lactate, citrate, tartrate, gluconate, camsylate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate and pamoate. In an embodiment, base addition salts include metal salts (such as sodium, potassium, aluminium, calcium, magnesium and zinc) and ammonium salts (such as isopropylamine, diethylamine, diethanolamine salts). Other salts (such as trifluoroacetates, oxalates and choline salts) may be used in the manufacture of compounds of Formula I and Formula II and their pharmaceutically acceptable salts and are included within the scope of the invention. All possible stoichiometric and non-stoichiometric forms of the salts of compounds of Formula I and Formula II are included within the scope of the invention. Acid and base addition salts may be prepared by the skilled chemist, by treating a compound of Formula I and Formula II with the appropriate acid or base in a suitable solvent, followed by crystallisation and filtration.

Some of the compounds of the invention exist in stereoisomeric forms. The invention includes all stereoisomeric forms of the compounds including enantiomers and diastereromers including atropisomers. The term homochiral is used as a descriptor, per accepted convention, to describe a structure which is a single stereoisomer. Absolute stereochemistry was not assigned in all cases. Thus, the compound is drawn at the chiral center as unspecified but labelled as homochiral and in the procedures it is identified by its properties such as for example first eluting off a normal or chiral column per the conventions of chemists. It should be noted that the provided experimental procedures teach how to make the exact compound even if not drawn with absolute configuration. Methods of making and separating stereoisomers are known in the art. The invention includes all tautomeric forms of the compounds. The invention includes atropisomers and rotational isomers.

For the compounds of Formula I and Formula II, the scope of any instance of a variable substituent can be used independently with the scope of any other instance of a variable substituent. As such, the invention includes combinations of the different embodiments. In some Examples, atropisomers can be observed and these are understood to convert at slow or fast rates or even not at all depending on the conditions for handling the compound. These are referred to as mixtures of atropisomers where they interconvert at ambient temperatures or as atropisomer 1 and atropisomer 2 where they were isolated. Since the compounds are identified by their properties rather than exact structural assignment from a crystal structure, it is understood in the art that where not specified, atropisomers are covered and inferred to be covered by the chemical structure.

In the method of this invention, preferred routes of administration are oral and by injection to deliver subcutaneously. Therefore, preferred pharmaceutical compositions include composition suitable for oral administration (for example tablets) and formulations suitable for injection including intramuscular injection.

The compounds and salts of this invention are believed to have as their biological target the HIV Capsid and thus their mechanism of action is to modify in one or more ways the function of the HIV capsid.

The compounds of the present invention and their salts, solvates, or other pharmaceutically acceptable derivatives thereof, may be employed alone or in combination with other therapeutic agents. The compounds and salts of the present invention and any other pharmaceutically active agent(s) may be administered together or separately and, when administered separately, administration may occur simultaneously or sequentially, in any order. The amounts of the compounds and salts of the present invention and the other pharmaceutically active agent(s) and the relative timings of administration will be selected in order to achieve the desired combined therapeutic effect. The administration in combination of a compound of the present invention and salts, solvates, or other pharmaceutically acceptable derivatives thereof with other treatment agents may be in combination by administration concomitantly in: (1) a unitary pharmaceutical composition including multiple compounds; or (2) separate pharmaceutical compositions each including one of the compounds. Alternatively, the combination may be administered separately in a sequential manner wherein one treatment agent is administered first and the other second or vice versa, and the different agents could be administered on different schedules if appropriate. Such sequential administration may be close in time or remote in time. The amounts of the compound(s) of Formulas I or II, or salts thereof and the other pharmaceutically active agent(s) and the relative timings of administration will be selected in order to achieve the desired combined therapeutic effect.

As such, the compounds and salts of the present invention may be used in combination with one or more agents useful in the prevention or treatment of HIV.

In another aspect, the present invention discloses a compound of Formula I or Formula II, or pharmaceutically acceptable salt thereof, for use in treating HIV infection wherein said method further comprises administration of at least one other agent used for treatment of AIDS or HIV infection selected from the group consisting of nucleoside HIV reverse transcriptase inhibitors, non-nucleoside HIV reverse transcriptase inhibitors, HIV protease inhibitors, HIV fusion inhibitors, HIV attachment inhibitors, CCR5 inhibitors, CXCR4 inhibitors, HIV budding or maturation inhibitors, and HIV integrase inhibitors.

Synthesis Scheme:

Step 1: Preparation of 2,6-dichloro-3-nitrobenzaldehyde

To a solution of sulfuric acid (H₂SO₄) (5.63 L, 4.5 V) in a round-bottom flask at 0-5° C. was added 2,6-dichlorobenzaldehyde (1.25 kg, 7.10 mol, 1.0 equiv.) in portions at below 15° C. The reaction mass was stirred at 0-5° C. for 30 min. A solution of freshly prepared nitration mixture [Prepared from Conc. H₂SO₄ (0.425 L, 0.34 V) and 70% HNO₃ (0.85 kg, 13.49 mol, 1.30 equiv.) at 0° C.] was added to the above reaction mixture at below 10° C. [Note: Reaction is slightly exothermic (3-6° C.); so that addition is preferred at lower temperature]. The reaction mixture was stirred at 5-10° C. for 2-3 h. After completion of the reaction (monitored by TLC), it was quenched with ice cold water (18.75 L, 15 V) at below 25° C.

The above procedure was repeated and the product from both instances was combined (825 g total), blended, and then purified by silica gel chromatography eluting with 5-10% MeOH in DCM. Fractions containing the desired product were pooled and then concentrated under reduced pressure to afford a yellow solid, 580 g, a mixture of atropisomers (diastereomers). A portion of this material (490 g) was mixed with methanol (5000 mL, 10V) and then filtered to remove the solids which were reserved. The filtrate was concentrated under reduced pressure to afford 255 g of the product, a ˜85:15 ratio of atropisomers favoring the desired atropisomer. This material was dissolved in methanol:acetonitrile (10:90, app. 1.5 L).

Biological Methods:

HIV cell culture assay—MT-2 cells, 293T cells and the proviral DNA clone of NL₄₋₃ virus were obtained from the NIH AIDS Research and Reference Reagent Program. MT-2 cells were propagated in RPMI 1640 media supplemented with 10% heat inactivated fetal bovine serum (FBS), 100 mg/ml penicillin G and up to 100 units/mL streptomycin. The 293T cells were propagated in DMEM media supplemented with 10% heat inactivated FBS, 100 mg/mL penicillin G and 100 mg/mL streptomycin. A recombinant NL₄₋₃ proviral clone, in which a section of the nef gene was replaced with the Renilla luciferase gene, was used to make the reference virus used in these studies. The recombinant virus was prepared through transfection of the recombinant NL₄₋₃ proviral clone into 293T cells using Transit-293 Transfection Reagent from Mirus Bio LLC (Madison, Wis.). Supernatent was harvested after 2-3 days and the amount of virus present was titered in MT-2 cells using luciferase enzyme activity as a marker by measuring luciferase enzyme activity. Luciferase was quantitated using the EnduRen Live Cell Substrate from Promega (Madison, Wis.). Antiviral activities of compounds toward the recombinant virus were quantified by measuring luciferase activity in MT-2 cells infected for 4-5 days with the recombinant virus in the presence of serial dilutions of the compound.

The 50% effective concentration (EC₅₀) was calculated by using the exponential form of the median effect equation where (Fa)=1/[1+(ED₅₀/drug conc.)m] (Johnson V A, Byington R T. Infectivity Assay. In Techniques in HIV Research. ed. Aldovini A, Walker B D. 71-76. New York: Stockton Press. 1990). The 50% inhibitory concentration (EC₅₀) was calculated by using the exponential form of the median effect equation where percent inhibition=1/[1+(EC₅₀/drug concentration)m], where m is a parameter that reflects the slope of the concentration-response curve.

Compound cytotoxicity and the corresponding CC₅₀ values were determined using the same protocol as described in the antiviral assay except that uninfected cells were used. Cytotoxicity was assessed on day 4 in uninfected MT2 cells by using a XTT (2,3-bis[2-Methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxyanilide inner salt)-based colorimetric assay (Sigma-Aldrich, St Louis, Mo.).
